I'm having trouble figuring out how to create a custom icon for a radconfirm dialog. I'm sure this is done in a CSS file somewhere, but cannot seem to find an example.

Can I simply set a property similar to this (I have guessed that this might be the property in question)?

    
            .radwindow a.windowicon
        
            {  
        
                display: block;   
        
                margin-right: 3px;    
        
                width: 20px !important;  
        
                height: 16px !important;  
        
                background-image: url(mynewicon.ico) !important;  
        
            }

Or am I offbase? I have searched but am unable to determine the answer.

Much obliged,
Joseph

Adding CustomAttributeNames throws error and breaks updating

As soon as I add the CustomAttributeNames (see code below), I can no longer double click the appointment to edit it.
Code:

    
                <telerik:RadScheduler ID="RadScheduler1" runat="server" DataEndField="EndTime" DataKeyField="ID" 
        
                    DataSourceID="sdsLessons" DataStartField="StartTime" DataSubjectField="Comments" 
        
                    HoursPanelTimeFormat="htt" Skin="Office2007" ValidationGroup="RadScheduler1" 
        
                    SelectedDate="2008-11-24" SelectedView="WeekView" Style="top: 0px; left: 0px"   
        
                    CustomAttributeNames="Subject,Text,StudentID,TextID">  
        
                </telerik:RadScheduler>

Error:
"Microsoft JScript runtime error:
Sys.WebForms.PageRequestManagerServerErrorException: Error serializing value 'Telerik.Web.UI.Appointment' of type 'Telerik.Web.UI.Appointment.'"

Any help would be great.

RadAjaxManager Error in FireFox

Hello,

In my application, I have the RadAjaxManager in the master page, and in all the content pages that use the manager, I define the proxy classes. When I load the application in FireFox, I get the error on the following line:

$create(Telerik.Web.UI.RadAjaxManager, {"_updatePanels":"","ajaxSettings":[<list omitted>],"clientEvents":{OnRequestStart:"",OnResponseEnd:""},"defaultLoadingPanelID":"","enableAJAX":true,"enableHistory":false,"links":[],"styles":[],"uniqueID":"ctl00$ram","updatePanelsRenderMode":0}, null, null, $get("ctl00_ram"));

The error I get is:

Telerik is undefined

Why might this be?

Thanks.

[Solved] Global place to put skin

Hello,

Is there a global place to put the reference to the skin that the telerik controls can use? For instance, can I stick the name of the skin that all telerik controls will use in the config file, and those controls get it from there? I'm just looking for an easy way to change the Skin as I setup the app in one skin, but most likely will change it to something else.

Thanks.

[Solved] Not answered Doubling of represented values in combobox

Hello!
The problem is - if I open combobox with selected value and click "ShowMoreResults" arrow or perform virtual scroll down, items with the same text as selected one appears in list. At the ItemsRequested handler number of items remains as it expected.
How can I prevent the behaviour described above?

[Solved] RadMenu NavigateUrl doesn't work in RadToolBar

When I place a RadMenu into a RadToolBar, the NavigateUrl of the RadMenuItem is never navigated to. I am using RadControls for ASPNET AJAX Q3 2008 (2008.3.1105.35). Is this a known issue? Do you have a work around?

<telerik:RadToolBar ID="tlbrMain" runat="server" Skin="Web20" Height="24px" >

RadGrid ItemUpdated error; object cannot be cast from DBnull to other types

I am using the latest Ajax Radgrid I have bound it to a SQLdatasource. I have stored procs for the update and delete methods of the gridrow. I am not allowing new records/inserts. The grid is also grouped by one field.

The problem I am having is the record may not exist yet in the database, so the datakey field may be null. But that is ok, in the stored proc if I see a null datakey field I assume its a new record and do the insert, otherwise I do an update.

So I click the edit button on the row, the boxes open up so I can enter data, then click the update link and BOOM. I get an error saying that the Object cannot be cast from DBNull to other types. Looking in the code behind page it blows up somewhere after the start of the RadGrid_ItemUpdated Event and before the SQLdatasource_updating event.

I need to be able to pass null values to the stored proc, even if it is the datakey field.

Thanks
G

Problem with AppointmentUpdate event

Hi, Here's my code. Actually, I call fresult = schedulingFacade.MoveVisit(ID, e.ModifiedAppointment.Start) in Case "1". The result is an error and Rollback my transaction and cancel AppointmentUpdate (e.Cancel). I don't know why but sometime (not always), appointment in calendar remains update. In my database, data is good (rollback is made) but in scheduler, appointment is not at the good place. Do you know why this append ?

Thanks

' get the facade we need

Dim schedulingFacade As ISchedulingFacade = SymoRequestContext.GetServiceLocator.GetService(Of ISchedulingFacade)("SchedulingFacade")

Dim ID As Guid = New Guid(e.Appointment.ID.ToString)

Dim fresult As FacadeResult = New FacadeResult

Try

TransactionManager.Instance.BeginTransaction()

Select Case e.Appointment.Attributes("aptType")

Case "0" 'Unavailability

fresult = schedulingFacade.MoveResourceUnavailability(ID, e.ModifiedAppointment.Start, e.ModifiedAppointment.End)

Case "1" 'Visit

fresult = schedulingFacade.MoveVisit(ID, e.ModifiedAppointment.Start)

Case "2" 'Stop point

fresult = schedulingFacade.MoveResourceStopPoint(ID, e.ModifiedAppointment.Start, e.ModifiedAppointment.End)

End Select

If fresult.IsValidResult Then

TransactionManager.Instance.CommitTransaction()

Else

TransactionManager.Instance.RollbackTransaction()

e.Cancel =

True

'Dim js As New System.Web.Script.Serialization.JavaScriptSerializer()

'Dim JsonErrorMessage As String = js.Serialize(fresult.ErrorMessage)

'Dim AjaxManager As RadAjaxManager = RadAjaxManager.GetCurrent(Page)

'ScriptManager.RegisterStartupScript(Me, GetType(BaseController), "showAlerts", "showAlert(" + JsonErrorMessage + ");", True)
